   1) How old are the belts and how have you been storing them? The glue on the joints can have a variable life.
   2)If they are new belts are you sure they are the correct length?
   3) Have you got the direction of rotation correct?

   i agree with phillip. It is either the age of the belts, or defective glue. Ask for a refund if they are new.

   Those belts don't do well if stored in high humidity.  I know.

   Sanding belt breakage can also be caused by worn bearings or bushings on the drive roller, maybe the idler roller as well.

   Retired until my next job.
